Abstract

The purpose of this work is to evaluate the potential of Global Positioning System (GPS) measurements for the monitoring of aeolian and coastal dynamics. The studied sites are the Moulouya estuary, Bouarfa’s area and Tigri Chott. The study shows that GPS is used to determine the dune kinematics and the Moulouya estuary in 3-D with an annual temporal resolution and a sub-centimeter accuracy. The GPS measurements carried out between 2013 and 2021 have shown spatial and temporal variations of the dune kinematics and Moulouya estuary. The results presented here show that the GPS measurements have the capability of continuously surveying the geomorphological entities’ kinematics with small and slow displacements and thus, they could complement conventional topometric techniques in a warning system.

Analysis of Chinese Citizens’ Perception and Its Differences of City Spirit: A Case Study of Hefei City DOI:  https://doi.org/10.30564/jgr.v5i3.4788 Abstract City spirit is the soul of the city. The spread of city spirit not only could establish a civilized specimen for citizens, but also create a good cultural atmosphere for the city. Hefei residents’ perception of city spirit is extensive, and most of Hefei citizens consider the expression words of city spirit are very appropriate, which is enlightened, open-minded, actual and innovate. Great majority of Hefei citizens willing to support the propaganda and promotion of the city spirit, and they think the promotion of the city spirit plays a key role in the way of city’s development. In addition,significant differences in the perception of urban spirituality emerge among residents with different economic and social characteristics. There are four aspects about how to enhance the public perception of city spirit, which including in...

Experimental Simulation of Red Sprites in a Laboratory

Experimental Simulation of Red Sprites in a Laboratory DOI:  https://doi.org/10.30564/jasr.v5i3.4858 Abstract Over the past three decades, research of high-altitude atmospheric discharges has received a lot of attention. This paper presents the results of experimental modeling of red sprites during a discharge in low-pressure air. To initiate ionization waves in a quartz tube, an electrodeless pulseperiodic discharge fed by microsecond voltage pulses with an amplitude of a few kilovolts and a repetition rate of tens of kHz were formed. In this case ionization waves (streamers) have a length of tens of centimeters. The main plasma parameters were measured at various distances along the tube. The measurements confirm the fact that ionization waves propagate in opposite directions from the zone of the main electrodeless discharge, just as it happens during the formation of red sprites.
